The ST stands for salt and troll. This rod holder is slightly larger than the Rod Holder Lite, and is great for any freshwater or saltwater rods - very versatile!
The Rod Holder ST uses a RAM ball-bearing mount to swivel 360 degrees with total up and down adjustments as well. Rod-lock ring keeps the rod totally secure and also has an adjustable back rod-butt stop in back. Keep your rods safe and secure with the Rod Holder ST!
